Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a rotatable and operable work lamp. Background Technology

[0002] In the present technology, work lights, as portable lighting devices, are widely used in maintenance, field operations, emergency lighting, and other fields. Typically, a traditional work light consists of a lampshade, a light source, and a switching device, with most using buttons or toggle switches for simple on / off control. For example, some rotary work lights use flexible hoses or ball joint mechanisms to adjust the angle of the lamp head to adapt to different lighting needs. In addition, there are handheld work light designs that emphasize portability and multifunctionality.

[0003] However, existing work lights still have several shortcomings: First, the switch operation is relatively simple, relying on manual pressing or tossing, which is prone to failure in humid or gloved environments, leading to inconvenience in use; second, the lamp assembly is fixed in position and cannot be flexibly extended or retracted according to the actual scene, limiting the adjustment of the lighting range and angle, especially in narrow spaces or high-intensity work, making it difficult to achieve precise lighting; third, auxiliary lighting functions are lacking or have poor linkage, and cannot automatically switch the on / off state of the main and auxiliary lamp assemblies, affecting the flexibility and energy efficiency of lighting; finally, the overall structure is relatively complex, making it inconvenient to carry and store, especially in folding or portable designs. Although existing technologies emphasize structural robustness, there are still safety hazards and low work efficiency issues. Utility Model Content

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0047] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0048] like Figures 1 to 7 As shown, the rotatable work light includes a lampshade 2 and a control device 3. The lampshade 2 protects the internal components while allowing light to pass through, and has multiple pre-drilled holes for the lamp assembly to extend or retract. The control device 3 is located inside the lampshade 2 and includes multiple first lamp assemblies 301 and a conical knob 302. The first lamp assembly 301 can use LED beads or other light-emitting elements to provide the main lighting source. The conical knob 302 has a conical structure, and its inclined surface allows it to drive the first lamp assembly 301 to extend or retract axially along the pre-drilled holes in the lampshade 2.

[0049] In actual use, pushing the conical knob 302 will drive the first lamp group 301 to extend axially along the reserved hole of the lamp cover 2 through the inclined surface of its conical surface. This design can save space and protect the first lamp group 301 when it is retracted.

[0050] In this specific embodiment, the work light also includes a base plate 5, which provides a fixed foundation and sliding support for the control device 3. The control device 3 also includes a screw 303, a base 304, a base fixing rod 305, and a slider 306. These components work together to achieve axial extension and retraction control of the first light group 301. The first light group 301 and the slider 306 are fixedly connected by screws or clips to ensure reliable motion transmission. The slider 306 is slidably fitted to the surface of the conical knob 302. When the conical knob 302 is rotated, the slider 306 moves along the conical surface, causing the first light group 301 to move. The base plate 5 is fixedly connected to the base fixing rod 305 by threads or welding, and is slidably connected to the slider 306 by a guide rail or channel, providing guiding and limiting functions for the slider 306. One end of the screw 303 is connected to the tapered knob 302 via an internal thread, and the other end is fixedly connected to the base 304 by welding or screws, which is used to convert rotational force into axial thrust; the base fixing rod 305 is connected to the base 304 in a similar fixing manner to form a stable support frame.

[0051] In actual use, the user rotates the conical knob 302, which rotates relative to the screw 303. Its inclined surface directly acts on the attached slider 306, pushing the slider 306 to slide. The axial displacement of the slider 306 directly drives the first lamp group 301 fixed on it to extend along the reserved hole of the lamp cover 2, ensuring smooth operation.

[0052] In this specific embodiment, the control device 3 also includes a conical knob cover 308 for covering and protecting the conical knob 302. One end of the conical knob cover 308 is connected to the conical knob 302 by a snap-fit, thread, or adhesive to ensure stability during rotational operation, while the other end is slidably connected to the lampshade 2. This design not only prevents dust, moisture, or other foreign objects from entering the control device 3 and affecting mechanical linkage, but also improves the overall protective performance and aesthetics of the equipment, and can seal the holes on the base plate 5.

[0053] In this specific embodiment, the control device 3 also includes a plurality of second lamp groups 307 as auxiliary lighting components, used to provide supplementary light sources when the first lamp group 301 is not in operation. The second lamp groups 307 are fixedly connected to the base plate 5, for example by welding, bonding or screw fixing, to ensure the stability of the light source in a vibrating or moving environment.

[0054] In actual use, the first lamp group 301 is completely contained within the lamp cover 2 when not in operation. At this time, the second lamp group 307 is lit. When the first lamp group 301 needs to be used, the conical knob 302 is rotated. The inclined surface of the conical knob 302 pushes the slider 306 to slide, causing the first lamp group 301 fixed thereon to extend out along the reserved hole in the lamp cover 2. The first lamp group 301 is in operation, and the second lamp group 307 is turned off.

[0055] In this specific embodiment, a switching device 4 is also included inside the lamp cover 2. The switching device 4 includes a connecting block 401. One end of the connecting block 401 is fixedly connected to the first lamp group 301 by screws, clips, or welding, for transmitting the axial extension and retraction movement of the first lamp group 301 to other components of the switching device 4; the other end is slidably connected to the lamp cover 2, allowing the connecting block 401 to move smoothly along a preset track of the lamp cover 2 without affecting the stability of the overall structure. This sliding connection design ensures that when the rotating conical knob 302 drives the first lamp group 301 to retract, the connecting block 401 can move synchronously and fit into the reserved hole of the lamp cover 2 to form a seal, preventing dust from entering and extending the service life of the first lamp group 301.

[0056] In this specific embodiment, the switching device 4 further includes a fixing block 402, a first limiting block 403, a second limiting block 404, a sliding plate 405, a spring fixing rod 406, a spring 407, a rack 408, and a switch control block 409. The fixing block 402 can be made of metal or high-strength plastic material. One end of it is fixedly connected to the slider 306 by screws or clips, and the other end is fixedly connected to the first lamp group 301 in a similar manner, ensuring that the axial displacement of the first lamp group 301 is reliably transmitted to the sliding plate 405 and the rack 408. The first limiting block 403 is fixedly connected to the base plate 5 by welding or screws, and is connected to one end of the spring fixing rod 406 to limit the position of the spring fixing rod 406 and provide an anchor point for the spring 407. Similarly, the second limiting block 404 is fixedly connected to the base plate 5 and is connected to the other end of the spring fixing rod 406, forming a symmetrical limiting frame to enhance stability. The spring fixing rod 406 and the slide plate 405 are slidably connected through a channel or bearing, allowing the slide plate 405 to move freely along the rod axis. The spring 407 is a compression spring, sleeved on the spring fixing rod 406, with one end fixedly connected to the first limiting block 403 and the other end connected to the slide plate 405, providing elastic restoring force to ensure that the slide plate 405 returns to its initial position after the external force is removed. The slide plate 405 and the rack 408 are fixedly connected by screws or integral molding, and further fixedly connected to the first lamp group 301, so that the extension and retraction of the first lamp group 301 directly drives the displacement of the slide plate 405 and the rack 408. The switch control block 409 is fixedly connected to the base plate 5 and electrically connected to the second lamp group 307 through a wire, used to control the on / off circuit of the second lamp group 307 according to the position change of the rack 408.

[0057] In actual use, when the first lamp group 301 is fully contained within the lamp cover 2 (i.e., in the non-working state), the rack 408 engages with the switch control block 409, forming electrical contact or mechanical triggering, activating the second lamp group 307 to illuminate. Conversely, when the first lamp group 301 extends, it drives the slide plate 405 fixedly connected to it to move, thereby driving the rack 408 fixedly connected to the slide plate 405 to move together. At this time, the rack 408 separates from the switch control block 409, causing the second lamp group to be disconnected and extinguished. Through the integration of the above components, the switching device 4 achieves automated lamp group switching, improving operational convenience and energy efficiency.

[0058] In this specific embodiment, the switching device 4 further includes an encoder 410, a gear 411, and a main shaft 412, used to convert mechanical displacement into electrical signals to monitor the extension degree of the first lamp group 301. The gear 411 is connected to the rack 408 through tooth meshing, converting the linear motion of the rack 408 into rotational motion, and is rotatably connected to the main shaft 412 through bearings or keyways to ensure smooth rotation and low friction. The main shaft 412 is connected to the base plate 5 through a fixed bracket or screws, providing rotational support for the gear 411 and maintaining the stability of the overall structure. The encoder 410 is a rotary or incremental encoder, and its monitoring end (input shaft or sensor interface) is connected to the gear 411 through a coupling or direct shaft to capture the rotational angle or speed of the gear 411 and output corresponding pulses or digital signals to accurately calculate the displacement of the rack 408, thereby indirectly monitoring the extension position of the first lamp group 301.

[0059] In practical use, when the first lamp group 301 telescopically drives the rack 408 to move, the gear 411 rotates accordingly. The main shaft 412 provides support, and the encoder 410 monitors and provides feedback signals in real time to control the circuit to adjust the lighting sequence of multiple LEDs on the first lamp group 301, achieving intelligent lighting adaptation. Specifically, the monitoring end (A / B phase output pin) of the encoder 410 is connected to the gear 411 via a coupling, outputting pulse signals. A microcontroller (MCU) is integrated on the circuit board of the base plate 5, using a low-power MCU such as an STM32F103 or Arduino Uno. The encoded signal is connected to the timer pin of the MCU, and the MCU's GPIO pins are connected to the LED driver chip to control the on / off state of each LED. The LEDs in the first lamp group 301 are arranged in a linear array, with each LED independently connected to the channel of the driver chip, supporting sequential lighting. The gear 411 meshes with the rack 408 and is fixed to the base plate 5. The rack displacement is converted into gear rotation, powered by a built-in lithium battery. The MCU provides a stable voltage through a voltage regulator module and adds a filter capacitor (10uF) to reduce noise interference. The encoder 410 captures the number of pulses, calculates the extension ratio (current pulse / maximum pulse), maps it to the number or sequence of LEDs lit, and uses an interrupt service routine to update the pulse count in real time to avoid delay.

[0060] In this specific embodiment, a folding frame 1 is also included to provide support and portability for the work light. The folding frame 1 may be made of lightweight metal or engineering plastic materials and features a foldable design for easy storage and transportation. It is fixedly connected to the conical knob cover 308 by screws, snaps, or hinges, ensuring the stability and durability of the connection. The folding frame 1 is equipped with three legs, each of which can be independently unfolded or folded, forming a triangular support structure to evenly distribute weight and enhance stability, suitable for uneven work surfaces. The leg design may also include anti-slip pads or adjusting screws to further improve support in wet or sloping environments.

[0061] Through the above structure, the integration of the folding frame 1 with the control device not only improves the overall portability and practicality of the work light, but also ensures safe placement in various work scenarios.

[0062] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
